As my existing ARM systems are getting a bit ‘old’ – being based on armv5 (DreamPlug) or armv6 (Raspberry Pi) – neither of which is supported by the most recent Fedora release, I have been looking for an armv7-based system for further development and testing.. After some experiences with promising designs that have – sadly – failed … Continue reading →
NVIDIA have just released driver 334.16, but – despite the fact that Kernel 3.13 has been released for some time now – the driver still fails to load correctly, with the same ”Unknown symbol acpi_os_wait_events_complete (err 0)” error.. So, the existing known/good kernel 3.13 patch still applies, except that the section of the patch relating to /uvm/nvidia_uvm_linux.h … Continue reading →
The ‘binary’ version of audacity supplied by certain distros lacks functionality, due to patent issues, so the best option is to compile it yourself.. For some time, there have been compatibility issues at compile time between the latest released versions of audacity and ffmpeg, on many systems.. For audacity version 2.0.5, on my systems (Fedora 20) the … Continue reading →
There is an article on DevZone that includes a possible Kernel 3.14 patch, from s_molgaard, for driver 331.38: https://devtalk.nvidia.com/default/topic/683534/linux/331-38-on-3-14-rc1-kernel/ The patch format is – apparently – for kernel boot-time patching using dkms, which I don’t use.. So.. I just manually applied the changes shown for nv-linux.h to the Kernel 3.13 patch mentioned in my previous article http://rglinuxtech.com/?p=1032, … Continue reading →
There have been several ‘Kernel 3.13’ patches on various sites for the latest NVIDIA drivers, and I have finally found one that – on my system – actually works, without causing uvcvideo / usb problems (see previous articles..) Thanks to the folks at ArchLinux, the patch can be found here: https://projects.archlinux.org/svntogit/packages.git/plain/trunk/nvidia_3.13_kernel.patch?h=packages/nvidia Be aware that there are other … Continue reading →
Just updated the DreamPlug to Kernel 3.14-rc1, and everything seems to work OK… Still getting a few mvsdio f1090000.mvsdio: unhandled interrupt status=0x0810 en=0x0000 pio=0 messages at boot time, but none after the system has booted… Fedora release 18 (Spherical Cow) Kernel 3.14.0-rc1 on an armv5tel (ttyS0) # uname -a Linux rgdreamplug 3.14.0-rc1 #1 PREEMPT Mon Feb 3 … Continue reading →
Just updated the test system to Kernel 3.14-rc1, and did the usual tests with the latest VMware (10.0.1) and NVIDIA (331.38). VMware compile failed with the VMware version of vmci, but this can be fixed by selecting the kernel.org versions of these modules, from the standard 3.14-rc1 source tree. The vmci module can be found under ‘Misc … Continue reading →
Just updated the DreamPlug and Raspberry Pi to Kernel 3.13.1. DreamPlug kernel from kernel.org, and the Pi from GitHub, as usual..
